Chemical weapons are abundant in variety. Their effectiveness is determined by several factors, including age, purity, weather conditions, and choice of dissemination. They include nerve agents, blister agents, and choking agents, all of which can be ingested through the eyes, lungs, or skin. Sarin, a type of nerve gas, was used by the Aum Shinrikyo cult in March 1995, killing 12 people and injuring more than 5,500 on a Tokyo subway.
化學(xué)武器種類(lèi)繁多。它們的效力是由幾種因素決定的，包括年限、純度、氣候狀況，以及散布途徑。化學(xué)武器包括神經(jīng)毒、皰毒和窒息毒，它們都能通過(guò)眼睛、肺部或皮膚被人體吸收。沙林是一種神經(jīng)性毒氣，1995年3月奧姆真理教在東京地鐵站使用，造成12人喪命，5，500多人受傷。
